EANDLE CONSTRUCTION FOB PLANES AND OTHER TOOLS.

Application filed May 8, 1909.

To all whom it may concern:

Be it known that I, CHARLEs B. STANLEY, a citizen of the United States,residing at New Britain, county of Hartford, State of Connecticut, haveinvented certain new and useful Improvements in Handle Construction forPlanes and other Tools, of which the following is a full, clear, andexact description.

My invention relates to a new and improved tool handle particularlyadapted to planes.

' The object of the invention is to provide a superior construction bywhich a strong and durable handle may be formed from composition whichwould otherwise lack sufficient strength in itself to resist hard usage.Ordinaril this material is molded from some suita le composition, and ithas been found that by reason of the fragile character of mostcompositions there is great loss due to breakage, not only occurringwhen the handles are applied to the planes, but also in after use. By myinvention the strain of the holding devices is effectively resisted, themolded or pressed composition of the handle being relieved of the same.

In the accompanying drawings Figure 1. is a vertical section of a planehandle constructed to embody my invention, a portion of the same beingshown in side elevation. Fig. 2 is an edge view of reinforcing meansdetached from the handle. Fig. 3 illustrates the same part and thereverse side from that shown in Fig. 1. Fig. I. is a section on linex--.t of Fig. 3, looking down. Fig. 5 is a view of the under side of thesame )art. In the drawings, 1 represents the grip por tion of thehandle, which may be of conventional form, said grip portion being madeof a suitable composition material molded or pressed to the desiredconfiguration. Arranged within the handle is a reinforcement of iron, orother suitable material, capable of withstanding severe strains and hardusage. This reinforcement is preferably of skeleton form and is soarranged as to furnish a backbone for the handle at all vulnerablepoints, and at the same time is available to receive the screwfastenings (not shown), by which said handles are secured to the planebodies. This reinforcement comprises the base plate 2, preferablyprovided with the feet 3-3, the ends of which feet are coincident withSpecification of Letters Patent.

' the bottom surface of the finished handle so as to act as a support.The plate 2 has an upwardly extending fin 4:, which extends through thegrip portion 1 of the handle and well toward the upper end thereof, asbest seen in Fig. I.

5 is an upper bearing for one of the fastening screws (not shown). 6 isa lower bearing for the same screw. The upper bearing 5 is coincidentwith the upper end of the grip portion of the handle, so that the strainof the screw head when'in place will be taken directly by the bearing 5,then by the web 4, then by plate 2, and fin ally by the bearing 6 andfoot 3. 7 is another bearing for another fastening screw, the upper endof this bearing being exposed at the upper surface of a forwardlyextending portion 1 at the base of the grip 1. This bearing 7 likewisetakes the strain of the head of the second screw, which 38.8368therethrough when the handle is applied.

The web 4, in order to insure lightness may be cut away, as at 88 thecut-away portion S being between the bearings 56. The two sides of theweb adjacent the cutaway portion 8 may have offset connections 9-9 toproperly tie together the two parts of the web, said connections beingoffset to afford clearance passage for the screw. These openings 88"permit the composition material to become more rigidly anchored to thereinforcement.

From the foregoing it will be seen that a handle thus constructed.possesses very great strength and durability, and the danger of breakageis reduced to a minimum. It will be also seen that the strain of thehold ing screws is taken Wholly by such parts and material as are bestcapable of withstanding the same. It will also be seen that thecomposition covering or envelop may be made from a material that wouldotherwise be unavailable because of too little initial strength, such,for exam le, as cork. These and other advantages Wil be apparent to theexperienced mechanic.

That I claim is:

1. In a tool handle, a grip of composition material, an interiorreinforcement having a screw passage therethrough from end to end of thegrip portion of said handle, said reinforcement carrying a bearing atthe upper and lower end to receive a fastening screw.

2. In a tool handle, a grip of composition material, an interiorreinforcement having a screw passage therethrough from end to end of thegrip portion of said handle, said reinforcement having a hearing at eachend to receive a fastening screw, and having a second screw passage, anda bearing for a second fastening screw, both of said bearings relievingthe composition covering of said reinforcement from the strain offastening screws.

3. A tool handle formed of composition material and having an inclosedmetallic rethe upper end of both screw passages ar= ranged to directlyreceive the strain of fastening screws. 7
